Abstract (en)
[origin: EP0405868A2] A ferroelectric liquid crystal is formed by incorporating, as the main component, a predetermined amount of a ferroelectric liquid crystal having a specific naphthalene ring structure into conventional liquid crystals. This liquid crystal composition has a broad driving temperature range and in particular; can be effectively driven even in a low-temperature region. Moreover, this liquid crystal composition has a high orientation uniformity, a high memory stability, and a high contrast ratio.
